VSELF-GENERATING VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 254,564, dated March 7, 1882,

Application tiled January 27, 1882. (No model.)

To all whom it may concern Be it known that I, WILLIAM P. PA'r'roN, of the city of Harrisburg, county of Dauphin, and State of Pennsylvania, have invented a new and Improved Self -Gcnerating Vapor- Gas Burner.

The object of this invention is to produce a brilliant light, free from smoke or smell, in a perfectly safe manner, using heavy crude benzine as an illuminating material.

I hereby declare the following to be a full, clear, and exact description of my improved burner, referencebein g made to the accompanying drawings, and the letters of reference marked thereon, in which- Figure 1 is a side elevation of the burner in Fig. 2 is a plan or top view of Fig. 3 is a side elevation of the burner in section. the gas-generating chamber and burner-tip in perspective, the hot-air jacket being removed. Fig. 5 is a side view ot' the burner-tip in perspective.

In the drawings, letter A represents the gasgenerating chamber. It is made preferably of cast metal, either brass or malleable iron. is given the form substantially as shown, having a vertical cylindrical portion, ct a', and two other parts, c d, also cylindrical in the body, that project from the vertical piece a a' in an axial line with each other and at right angles to the piece a a', as is shown in Figs.` 3 and 4. The vertical part a a ot' the gas-generating chamberA is perforated with a hole of a proper Size. The diameter of this perforation is larger at the upper end, and continues of such enlarged dimension to a point just below the junction of the projections c d. From said point through to the lower end the hole is made of a diminished size, as shown at o in Fig. 3. The upper end of the vertical bodya a. is threaded upon its outside, as is shown in Fig. 3 at a. Thelaterally-projecting portions c d are made a proper diameter and are perforated axially, the portion c being tapped or threaded for the reception of a taper-pointed set-screw, E. (See Fig. 3.) This set-screw is intended to act as a valve to control the inux of benzine, and the point must be made true with the center of the body and the threaded Fig. 4 shows the body ofv Ity `portion be well fitted to its place, so as to be gas-tight and yet move readily by application ot'- the hand of the operator to the thumb-piece D. (See Fig. 3.) The other or conical-tapered end is made to accurately tit into, so as to perfectly close up, the small perforation e in the center of part d. This small perforation e forms a diminutive passage or communication between the vertical hollow chamber t a and the feed or supply pipe C. (See Fig. 3.) Said pipe C is screwed tightly into a threaded hole made for its reception in the body of the portion d. The pipe C should be packed with wire ot' a fine gage, so as to restrain the free flow ot' naphtha or benzine, either of these volatile fluids being suitable for use in my improved burner. Again, this packing prevents the gas generated l'rom forcing back into the elevated tank from which the burner is fed. The lower end of the vertical part a a is provided. with a small hemspherical cup, F. (See Figs. 1,3.) This cup is rigidly attached to the lower end of a', and is intended to contain a smallquantity the orifice n can be perfectly closed again by moving inward the point of screw G.

The burner-tip J (see Figs. 3 and Aat) is constructed preferably of thin metal plate. It is made up of two separate pieces. The upper portion, h, is stamped up from a single disk of sheet metal, brass plate preferred. lt is given the form substantially as shown in the drawings. (SeeFigs.3,4,and 5.) As represented, the tip has a rounded edge, and the body resembles a hemisphere that is flattened somewhat upon two opposite sides. The base ot' this upper portion of the burner-tip is eX- tended so as to form a flange, m. The cone J is divided by a ne slit, s, made through the body. This slit extends downwardly to within a short distance from the base-flange m. As it is of importance that the'slit in this rooi piece should be of such width as only to permit the vapor gas to escape through it under considerable pressure, I have found the best results to be obtained by cutting said slit with a saw the blade of which is (100) one-hundredth part of one inch in thickness, with very tine teeth. The lower portion, p, of the burnertip J is made of sheet metal, the same as the upper, h, and is cylindrical in form, with a pro- IO jecting ange, 1', formed upon its upper end at a right angle to the cylindrical part p. The flange 1 extends outward a proper distance, and is raised atits edge, so as to receive and retain the upper piece, h, by being riveted or tightly pressed inwardly upon and over the edge of llange m. (See Fig. 3.) The lower or cylindrical part, p, is threaded on its inner surface, so as to permit it to be neatly screwed down upon the threaded upper end of the gasgenerating chamber A at a. (See Fig. 3.)

Upon the outer ends of the portions c d of generator A a cylindrical sheet-metal jacket, L, is rigidly secured. This jacket or sleeve is made of a proper relative length to that of the generator A, and upon its upper end is mounted a sheet-metal dome or heat-dedecting cone, O. (See Figs. l and 3.) Said coneO is made of a proper relative height to the top edge of the slitted burner-tip J, so that a sufficient airspace is allowed between its inner surface and the upper edge of the tip J. The cone O is also slotted a proper width andlength to permit the gaseous flame to escape from the burner-tip J. The slit in the burner-tip and the slot in the cone 0 should be so adjusted that the cone-slot will locate directly over and in right line with the slit in burner-tip J.

As my improved vapor-burner will be used principally in glazed lanterns for street-lighting purposes and other similar uses, a properly-constructed lantern must be provided, a tank for receiving and delivering naphtha or benzine to the burner being properly secured to said lantern-frame in an elevated situation, soas to deliver its contents through a pipeand regulating-cock to the feed-pipe of the burner, the saine being rigidly secured thereto by screw-thread or other similar method.

The elevated tank being filled, the manner of operating or lighting the burner is as follows: The ordinary cock that is attached to the feed-pipe C being opened, the fluid (gasoline or benzine) will [low through said pipe to near the generator-body A. The cone-pointed valve-screw E being Withdrawn a slight distance from contact with its seat, benzine (or naphtha) will dow into the hollow body of the generator A. By then opening the small lower cone screw -valve, G, a sufficient quantity of the benzine (or naphtha) can be supplied to partly ll the cup F. The valve E being now adjusted to nearly cut oft the tlow of the benzine, the valve G entirely shut, the fluid in the cup F should be lighted. The resulting flame will be conducted upward, in close c'ontactwith the generator-body, by the jacket L acting as a draft-flue or chimney. In a short space of time the benzine will be vaporized or gasitied by the surrounding heat, and as the generatorchamber has no other outlet, the highly raretied carbon gas will be expelled with force through the narrow or line slit in the burnertip J and be instantly' lighted. The heat conducted by the various parts from the flame to the generatorcauses a continuance ofthe formation of vapor gas therein. The rarefaction of the air around the llame causes an upward draft in the jacket L, and the heat of the llame in contact with the deilectorcone O causing the cone and jacket upon which it is mounted to become hot, the upward current of air is highly heated, and, rising, produces a draft of air, and thus furnishes oxygen in sufficient quantity to cause perfect combustion of the carbonaceous vapor gas. My burner is so perfect in principle that heavy crude benzine of 650 specific gravity can readily be burned in it, furnishing a rich, soft, white light or flame of high candle-power.

I do not desire to broadly claim devices that vaporize naphtha by burning it in unprotected burners the bodies of which are exposed to the cold currents of air surrounding them.

I am aware that there are several gasolineburners of that description patented. In operation all such devices are imperfect, as they fail to properly heat the air before it comes in contact with the gaseous carbon flame, and

consequently the supply of oxygen is insuy cient, and the flame is `smoky and flickering, and light produced of low candle-power.

What I do desire to claim as new, of my invention, and desire to secure by Letters Patent of the United States, is

1. The combination of the vapor-gas-generating chamber A, thin -slitted burner-tip J, heat-deflecting cone O, and feed-screw E, substantially as is herein set forth, and for the purpose specified.

2. The combination of the gas-generating chamber A, in which carbon vapor or gas is evolved by heat unmiXed with air, with the thin-slitted burner-tip J, hot-air jacket L, heatdetlecting cone O, and feed-screw E, the wholer being constructed and operating substantially as is herein shown, and for the purpose set forth.

3. The combination of the carbon-vapor-gasgenerating chamber A, heatdetlecting cone O, hot-air jacket L, burner tip J, feed screw E, charging-valve G, and receiving-cup F, the whole being made and operating substantially in the manner and for the purpose specied.
